Given numbers are 687, 296, 885, 642

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(687, 296) = 203352

GCD(687, 296) = ( 687 x 296 ) / 203352

= 687 / 296

= 687

Step2:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 687, 296, 885, 642 is 1
